An invention is an innovative idea (i.e. an original idea of its inventor) which has become a reality! It just takes 'a necessity', a problem that needs a solution to make life easier or more comfortable, a curious person with a 'divergent' turn of mind, the needed resources (i.e. materials), and the background knowledge because, whether we like it or not, every 'new' invention is based on knowledge acquired in previous experiments!
